It would be the reverse of wisdom to claim ad ignorantiam as proof of Santa Claus. Likewise for Tarot's origins as a form of Qabalah. The point made above is that an unbridgeable gap exists between occultists and serious historians so long as the former keeps hidden what the latter must see in order to believe. Both may refer to the same deck of cards, but each possesses a different sense for what those cards mean. And no amount of ad hominem will ever succeed in bridging that gap. Yet, if Tarot can be utilized to reveal a hidden rationale underpinning both the symbolism of Freemasonry and the sequence of Hebrew Letters, it would benefit the serious historian to learn how that methodology works considerably more than arguing from incredulity.
It can be demonstrated that distinct mathematical & geometrical properties arise from the Hebrew alephbet when the Tarot de Marseilles is applied as a “cypher” [aleph=0]. Properties which are reflected in the iconography of the cards themselves, and which have a direct bearing on the Great Pyramid at Giza. While this does not prove that Tarot cards have existed since the time of the Old Dynasty pharaohs, it does offer a reasonable explanation for why certain notable occultists have maintained that they represent a kind of Book written by the mythological inventor of Letters & Numbers.
non haec sine numine divum eveniunt
I must agree with Mary, what you are saying is not based on empirical knowledge. Were a link found, even a little jotted note in the corner of a card saying anything that connects Tarot and Kabbalah, I would see something there, but unfortunately, there isn't. Again, it works, but I don't know how or why, and I suspect the combination is not "natural," as in, both the cards and the Tree of Life had to be "raped" somewhat in order for the attributions to work (it was certainly done to the Wheel of the Zodiac in order to accommodate the new attributions). Not only that, but the number of cards wasn't always uniform and has changed over the centuries, until Ettiella (and others), in a way, "codified" Tarot and brought it to its present state.
In addition, not to be, again, harsh, but it would be good if you could cite your sources about the Great Pyramid and other ideas. I'm not saying you're wrong, but if there is anything remotely Tarot on the Pyramid, it would interest me very much!
